1 Claim. (Cl. 50-171) This present invention relates to corner trims used in building constructions finished with shake, cedar, slate, and asbestos shingle siding.

The primary object of the invention is to provide a corner trim having a base that will align with the bottom edge or shadow line of the shake.

A further object of the invention is to provide a corner trim of the class described above having means therein holding the trim tightly against the corner of the shake covered walls.

Another object of the invention is to provide a trim member having means to hold the bottom edge thereof from moving transversely of the corner of the building and the shingles.

A still further object of the invention is to provide a corner trim having means at the lower edge there for holding the corner trims to the lower edge of the shingles without the use of nails or separate fasteners.

Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings in which:

FIGURE 8 is a fragmentary side elevation of the invention in applied position illustrating how the bottom edge of the trim is squared off with the lower edge of the shingle.

FIGURE 9 is a perspective view of a tool used to apply the trim to the under edges of the shingles.

FIGURE 10 is a view similar to FIGURE 3 illustrating the modifications of FIGURES 5 and 6.

FIGURE 11 is a fragmentary perspective view of still another modified form of the invention.

FIGURE 12 is a view similar to FIGURE 3, illustrating the modification of FIGURE 7.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral 10 indicates generally a corner trim constructed in accordance with the invention. The corner trim 10 is vertically elongated and is adapted to fit over the corner of buildings of the type illustrated in FIGURES l and 8. The corner trim 10 has a pair of integral legs 11 and 12 formed at right angles to one another along a corner line 13. The legs 11 and 12 taper toward upper ends 14 thereof. The legs 11, 12 are each bent inwardly at their lower ends into a horizontal portion 15 at an acute angle to the legs 11, 12 referring particularly to FIGURES 4 and 5. A portion 16 is bent upwardly from the inner edges of the horizontal portion 15 to lie parallel to the respective legs 11 and 12 and carries a reverse bend portion 17 on its upper edge in the form illustrated in FIGURES 2, 3, 4. and 11.

The corner trim 10 is applied to soft material, such as cedar shingles 23 and has upwardly turned lips 18 formed integrally on opposite ends of the horizontal portions 15, as illustrated in FIGURES 2, 3 and 4.

Detents 19 are punched along the portion 16 to extend towards the legs 11, 12. The detents 19 enter the shingle 23 to assist inpreventing the trim 10 from moving laterally with respect to the shingle 23. The detents 19 can be used in combination with the lips 18 or alone and the lips can also be used alone.

Inthe use and operation of the invention, shingles 23 are applied as illustrated inFIGURE 3 with the shingle 23 lapped down over the inner backing-board 24. The upper end 14 of the trim 10 is nailed to the shingle 23 and the wall by nails 26, after the trim 10 has been applied to the first course shingle 23 and before the second course of shingles 23 and backing-board 24 are applied.

After the shingles 23 have been applied to form a corner, the trim piece 10 is applied by forcing the portion 16 formed on the horizontal portion 15 up under the lower edge 25 into the space 29. The portion 16 is in contact with the inner face of the shingle 23 adjacent the lower edge 25, While the lip 18 is forced up into the shingle 23 at 28, also the detents 19 enter the inner surface of the shingle 23. Both the lips 18 and detents 19 when used together prevent the trim 10 from moving laterally or sidewise of the shingles 23, thereby securing the trim 10 to the lower edges of the shingles 23 without the use of nails. The reverse bend portion 17 is semi-resilient and biases the portion 16 against the inner surface of the shingle 23. The reverse bend portion 17 engages against the face of the upper end 14 of the next lower corner trim 10.

A special tool 30, illustrated in broken lines in FIG- URE 3, and in perspective in FIGURE 13, is used to force the corner trim 10 up under the shingle 23. An inner upwardly extending leg 31 is engaged against the underside of the reverse bend portion 17 and an integral horizontal portion 32 engages against the under surface of the horizontal portion 15. The operator presses against an integral upwardly extending portion 33 of the tool 30 holding the tool snugly against the corner of the buiding while he uses a hammer to strike the under surface 34 thereof. This insures an even pressure to all portions of the trim 10 and prevents distorting thereof.

It will be noted in FIGURE 8 especially, that the horizontal portion 15 is bent into an acute angle with respect to the legs 11 and 12 so that the horizontal portion 15 will be parallel to and align with the bottom edge 25 of the shingle 23 while the legs 11 and 12 will lie parallel to the respective faces of the shingles 23.

The modification illustrated in FIGURE 11 is essentially the same as the preferred form of the invention illustrated in FIGURES 1 through 4 with the exception that the lip 18a is struck out of the horizontal portion 15 instead of being formed on the end thereof. The lip 18a while shown adjacent the end of the horizontal portion 15 may be spaced from the end when desired.

The modification illustrated in FIGURES 5, 6 and 10 is used with shingles 23b of conventional construction having no space 29 behind the lower edge thereof as in the preferred form of the invention. A corner trim 10b is provided with integral legs 11b and 12b, an upper portion 14b and horizontally extending lower portion 15b. Portions 16b extend upwardly from the inner edge of the horizontal portion 15b. The outer end edges 20 of the portions 16b are bent toward the legs 11b and 12b, respectively, to form lips 21 which bite into the shingle 23b to lock the corner trim 10b against lateral movement 3 thereon. The portion 16b has detents 19!: identical to detents 19 for locking against the inner face 'of'the' lower edge of the shingle 23b. The corner trim 10b has the upper end 14b thereof secured by means of vnails 26b.

The modification illustrated in FIGURES 7 and 12v is identical to that illustrated in FIGURES 5, 6 and 10 with the exception that lips 22 are formed on the opposite outer ends 20 of the portion 16b and the lips 22 extend oppositely from the legs 11b, 12b, respectively, for locking engagement with a backing-board 24b. In this modification shingle 230 is of hard material such as asbestos cement which would resist peneration of the lips 18 and 21 of the previously described modifications.

Having thus described the preferred embodiments of the invention, it should be understood that numerous other modifications and adaptations may be resorted to without departing from the scope of the appended claim.

What is claimed is: p
